National Science Foundation Headquarters



Protective Design, which became a Thornton Tomasetti practice in September 2015, provided blast engineering on a fast-track design and construction schedule for the National Science Foundation Headquarters. The 56-acre campus includes two towers (14 and 19 stories tall) connected by a central link, 30,000 square feet of retail, and three levels of below-grade parking for 380 vehicles. This project is seeking LEED Silver certification.

Maximum Protection, Minimum Risk
Our engineers established and implemented project-specific blast design criteria based on ISC Risk Management Process for Federal Facilities standard. These criteria maximize protection to occupants while minimizing risk and meeting the project budget. We performed blast engineering design and offered value engineering options for exterior windows, curtain walls, precast panels, and structural framing members. We employed finite element engineering models to design upgrades for transfer girders and columns to minimize changes to the column grids and framing layout.
